SHAVING IMPLEMENT.

application mea March 3 1, 192s." serial No. 266,233.

This, invention relates to an improved shaving implementthat has a shear plate that rests against the face and has a cutter operating under the plate to cut the hairs.v

ing plate or its equivalent is extremely thin.

The thin plate isheld in place against ilex- .ing and collapsing under inward pressure'by the cutter which is disposed inside the shearing plate' to co-operate with it in shearing and to support it against flexing.

The invention also comprises various details of the construction which details will be more fully set forth hereinafter and will also be embodied in the claims.

The invention is illustrated in the accompanying drawing in which Figure l is a Aside view of a shaving implement embodying my invention. Figure 2 is a bottom view thereof. Figure 3iis an' enlarged se'ction of the shaving head f the machine and *Figure 4 is a transverse section on line 4 4 in Figure 3. Figure is a still larger showing of the detail of the shear plate and the cutter and Figure 6 is a perspective view of a part of the cutter shown in Figures 2 and 3. Figures 7 and 8 are longitudinal and cross-sections of a modified form .of cutter..

Figure 9 is another modification of cutter. The implement or machine is constructed to shear close to the skin to accomplish a close shave and in order to do this I prolvide a very thin shear plate or its equivalent, this plate resting on the skin and having an opening or openings against the edge of which a cutter operatesto cut the hair. The shear plate is so thin that it would collapse or Hex under inward'pressure and the cutter is therefore disposed in a way to support the shear-plate over its inner surface.

The preferred form is to have the cutter sup port the shear-plate over practically its entire surface at all times. A

The device is constructed to present a sheanplate for movementalong the skin, which plate has slots with both ends open. This form therefore provides a plate with no defined front or back but which can be moved back and forth across the skin and can therefore rest close to the skin and the hairs that aref. still uncut 'and in the slots do not raise the -device out of close Contact Wlth the skih. This allows 'a very close shave to be accomplished. The inside cutter that operates across these slots and transverse relative to the direction of movement of the machine cut-s across the edges of the slots to sever the hair, the slots being close together to form a series of narrow teeth which are prevented from moving inwardly by the support given by the inside cutter, which cutter has its teeth arranged on the end as differentiated from prior cutting devices in vwhich the movable cutters have the teeth operating alongside the shear plate.

The device comprises, in its preferred form, a handle 10 on the end of which is the shaving head 11. On the end of the shaving head 1s the shear-plate 12 which in this instance 1s shown as a series of parallel blades 13 on the end of the U-shaped piece 14.

The blades 13 are formed by cutting parallel slots Macross the end of the piece 14a. This plate 13-can be provided with openings of other shapes as will be evident but this form 1s though to be the easiest and cheapest to make. i

The plate 12 is made extremely thin and when used a ainst the skin the skinA forms a cushion so t iat the shearing or cutting edge which is on the inside faceof the plate is pract1cally flush with the surface of th'e skin. The blades 13 are too close together, however, to allow the skin to pass up into the slots 14 and the skin is therefore safe from cutting. The angle of the blade edge sloping about as shown in Fig. 5 has been found advantageous in practice.

The cutter can be of a design to co-operate with the opening or openings inthe shear plate` and is arranged to support the shear plate 12 from the inside. This prevents exing and bending `of the shear plate and thus provides a firm and smooth-feeling surface presented to the skin.

-The cutter in this form comprises a bar 15 which is c ut away as at 16 to form teeth 17 which lteeth pass across the edges of the blades 13 to shear the hair. The teeth are arranged so that a tooth passes over an openf ing in one direction and. shears against one edge of the opening and moves far enough to uncover the other edge of the opening and this causes the teeth to bear at a l times on a major portion of the blades 13 as one tooth engages'a blade-before the preceding blade `inclined at the top to direct the out hair to.

the slot 18 in theside wall of the shaving head 11 from'which it falls or from it.can be conducted by a flexible tube which in turn might be connected to a vacuum pump.

The cutter' rcciprocates in the U-shaped member 14a and is mounted on a bar 19 which acts as a support for the cutter and which carries means such as the screws 20 and the soft metal plate 21 for adjusting the cutter when it wears. The vU-Sllaped piece and the bar 19 can be held in place by the screws 22 between the side-pieces of the shaving head 11. This enables the'U-shaped piece and its contents to be taken out as a unit whenever it is necessary to do so by simply removing the screws 22.

The cutter is reciprocated and I show the shaft 23 for the purpose, one end having an eccentric stud 24 in a transverse slot in the cutter so that when the shaft rotates the cutter is moved back and forth across the blades 13. The shaft extends into the handle and can have any form of attachment for a flexible shaft such as exemplified by' the bars are arranged so that the teeth in one bar are opposite the recesses in the other bar so that they are staggered to insure the support of the blades 13, bot-h bars being adapted to feed the cut hair through the recesses and out through the openings 29 in the sides of. the shaving head 11.

Another modification is shown in Figure 9 in which two parallel bars are cut away to form teeth and between them I arrange a continuous strip 30, this strip being Without recesses or teeth and forming a solid support for practically the entire length of the shaving head whereby all the blades are supported at the centre.

In these various modifications the ends of the teeth are flat so as to give a maximum surface bearing against the inner faces of the blades 13. The blades 13 are made of extremely hard material to form a series of keen cutting edges and when the end of the shaving head is passed over the face a close comfortable shave is accomplished.

vIn shaving devices that are to be used on long hair such as in clippingr as distinguished from shaving the plate is of course made of` material thickness and can support itself.

The use of1 a relatively thin plate with a cutter operating under it and offering the easy adJustment possible in this case is novel. The old-fashioned clipper is cumbersome and forms such a broad and deep surface that it can not be used to clip with comfort in recessed places or where obstructions are offered. The use of a flat cutter operating in conjunction with a narrow shear-plate also offers advantages apparent to one familiar with the use of suchl implements.

It will be understood that modifications can be'made in the construction of the implement las shown without departing from the scope of the invention.
